Have any of you shot a 444 marlin in a 410 shotgun? I've seen it done with an old Brazil made 410 and the barrel was checked with a micrometer before and after. No change in the muzzle size. I have a new Iver Johnson 410 and I thought I'd ask around before I tried it. Of course I was going to put the 410 in a vise and pull the trigger with a string the first few times. Any advice or warnings?
